The Safety Palette

For reference, this section quickly mentions the safety palette, which is a very commonly used default palette. To use the safety palette, you set six equally spaced possible values for each color component: 0, 51, 102, 153, 204, and 255. In other words, the red component can have any of these values. The green component can have any of these values and so can the blue component. Possible colors from the safety palette include (0,0,0), black; (153,0,0), a fairly dark shade of red; (0, 255,102), green with a smattering of blue added; and so on. This gives you a total of 6 cubed = 216 colors. The idea is that this provides an easy way of creating a palette that contains colors from right across the spectrum and of all degrees of brightness. ....
